The background: Holy Ghost! are remixers and musicians in their own right who thoroughly deserve that exclamation mark. The songs on their MySpace comprise the best music we've heard by a disco-obsessed US act since we first brought Hercules & Love Affair to your attention at the start of last year. They used to be in a rap group, formed at high school and inspired by their hero J Dilla, called Automato, whose debut album was produced by Tim Goldsworthy and James Murphy of the great DFA, label home of LCD Soundsystem, Hot Chip and the Juan MacLean. This prompted Millhiser and Frankel to get involved in a variety of DFA productions and they became touring and recording members of the Juan Maclean. They've done brilliant remixes for Moby, Phoenix, MGMT and Cut Copy, and they had one of their own tracks, Hold On, featured on a compilation from French electronic dance imprint Kitsune. Now they're working on an album of their own music and preparing to play live, both of which will demonstrate their love of analogue synthesisers, rare disco and what they describe as "ancient production techniques".

Basically, their MySpace tracks and Hold On, which you can hear on Spotify, reflect a twin love of cool, clean, synthed-up dance and the warmer, more organic variety beloved of late-70s New York. It's a schizoid agenda, but it works. Hold On would have fit quite nicely, thank you, on the recent, superb album of Human League-ish electro-pop by the Juan Maclean, whereas a lot of Holy Ghost!'s reworkings of other people's material keep things beautifully pure, the bass, beats and brass stabs luxuriating, untreated, in the usually spacious mix. Some of their tracks use both approaches: there's one called The Deep End, the provenance of which remains a mystery – and no one loves original disco like we do up here – which has all the elements you could wish for from a slice of Studio 54-style nirvana, handclaps, strings, repetitive guitar figure and all, but there's also a sprinkling of cosmic keyboards that's pure Italo disco and a processed bassline that sounds as though it's on loan from early New Order. Meanwhile, they do amazing things to Phoenix's Lisztomania. We're also major fans of the French pop maestros, but we couldn't help feeling that their Wolfgang Amadeus Phoenix was a bit of an unnecessary rocky departure, so we're delighted by what Holy Ghost! do to the opening track of the album, affording it a lustre and lissom groove it previously lacked. Maybe they should do a League Unlimited Orchestra and remix the whole album for them ...

The buzz: "Holy Ghost! are the freshest, best-kept secret of DFA and the Big Apple. Mating house, disco and tight indie jeans for a mesmerising dance outfit ..."

The truth: They should do a vinyl concept album: the one side warm and organic, the other cool and electronic. We should be in marketing, you know ...

Most likely to: Make Phoenix want to kick themselves.

Least likely to: Make Bianca Jagger want to strip naked and ride a white horse through a nightclub, in 1977.

What to buy: Check out their remixes on their MySpace and a couple of their original tracks on Spotify.
